Bug: Contour command crashes rhino

When running contour command rhino abort it and displays the following message

Any one has the same issue? or know a way to fix this kind of bug (registry manipulation, etc)

Hi -

Please run the Rhino SystemInfo command and copy-paste the result here.
Also, I ran a quick test on Rhino 7 and wasn’t able to get that message to display. Can you reliably reproduce the issue? If so, please also post a 3dm file and steps to follow.


It looks like it was the vray plugin that was causing the conflict. Installed the latest (20220118 today) and it solved the issue.


It was our fault and not Vray. Sorry for the inconvenience. The contour command is undergoing some changes to try and solve sections using multiple cores.

Thank you for the precision.
